摘要: 本文总结了渤海湾盆地下第三系的演化和发育特征,认为沉积物重力流沉积体系发育,湖泊风暴岩也可成为良好储层.叙述了新地层学原理(垂向加积作用和侧向加积作用)在油气勘探中的作用.讨论了渤海湾盆地下第三系陆相碎屑岩的埋藏成岩作用,对储层空间的形成机理提出了新的认识,认为砂体微相和成岩作用共同控制着储层物性变化.并进一步指出了储层地质学在油气勘探中新的作用.

Abstract: In this artical the characteristics of evolution development and of lower Tertiary in Bohai Basin was summarized and it is pointed out that the gravity flow sediments was widely developed and the lacustrine tempestite can be good reservoirs.It was considered that the new principle of straigraphy(verticle accretion and lateral accretion)will play an important role in petroleum exploration.Through the discusion of diagenesis of depositional sediments,a new view point is suggested about mechanism of formation of the pore space in a reservoir,it is considered that the petrophysical properties of reservoir is control led by both micro-sedimentary facies and diagenesis.It is pointedout that reservoir geology plays a more important role in petroleum exploration and development.
